Tax Appeals

ASI has now completed the revaluation of all properties in the Borough. Assessment postcards were mailed to every property owner on April 3, 2020 setting forth your new assessment.  If you feel your tax assessment is improper, you have the option of filing a tax appeal with the Passaic County Board of Taxation.  Appeals are ordinarily due 45 days from the date your assessment postcard is mailed.  Based upon an Order issued by the Chief Justice of the New Jersey Supreme Court, that date has been extended to 30 days following the lifting of the declared State of Emergency.  Governor Murphy, by Executive Order 119, extended the State of Emergency to May 7, 2020.  As such, any tax appeal must be filed on or before June 8, 2020.  If the State of Emergency is further extended, the time period for filing an appeal will likewise be extended.  We will provide an update on this website if that is the case.  Below you will find important links to assist you in filing an appeal.  You will find the Petition for Appeal form, a link for NJACTB.ORG, which will allow you to look up an assessment for any property in Hawthorne, and the link to the ASI website, which performed the revaluation, listing all new assessments and sales lists.  If you require a copy of your new Property Record Card, you must submit an OPRA request form to the office of the Borough Clerk.  You can find the OPRA form on this site as well.  If you have any further questions regarding your assessment, you may email the Borough Assessor, Tim Henderson, at
